UNITED STATES PATENT OFFICE.

TO'ITEN POLING, OF MENLO, IOWA, ASSIGNOR OF ONE-HALF T0 H. N. ROSS, OF SAME PLAGE.

RUNNING=GEAR FOR WAGONS.

SPECIFICATION forming part of Letters Patent No. 273,599, dated March 6, 1883. i Application tiled November 24, 1882. (No model.)

To all whom vit may concern:

Be it known that I, ToT'rEN POLING, of Menlo, in the county of Guthrie and State of Iowa, have invented an Improved Wagon- Gear, of' which the following is a specification.

The object of my invention is to save time and labor in the construction ot' a wagon or carriage, and to torm a exible gear that will allow its wheels to successively rise and fall 1o in passing overobstructions or advancing over.

a rough, uneven, or laterally-inclined surface without disturbing the level and balanced position of the box or body ofthe wagon or carriage orsubjectingthe persons or freight thereon tojars and concussions and displacement. It consists, first, in for'ning and combining a duplex spring-bar with an elliptic spring at the front partof the gear in such a manner that the spring-bar and box or body thereon zo will have a vibrating motion relative to the spring and front axle; second, in the manner of combining the hind end ofthe wagon with a reach by means ot' a swivel-coupling in such a manner that the rear axle will have a vibra-A tory motion relative to the reach and the box or body, all as hereinafter fully set forth.

Figure l is a top view ot' my improved gear. Fig. 2 is a transverse section ot' the front part of the gear. Together they clearly illustrate 3o the construction and operation of' my complete invention.

A represents the front axle of a vehicle.

Bis an elliptic spring of' common f'orm.

U O are curved and rigid 'metal bars, having eyes d formed in or fixed to their centers, as clearly shown in Fig. 2.

ff are straight bars and struts that serve as chords to connect the ends ot the curved bars C. They are fixed to the bars O by means of' screw-bolts, or in any suitable way as required to support a box or body.

g is a metal plate that has gudgeons h extending` laterally in opposite directions from its center. To combine the bars C with the spring B, and to produce a complete duplex and vibrating spring-bar, I bolt the plate g upon the top and center ofthe spring, and then hang the bars upon the gudgeons h by means of' theeyes or bearings d, and connect 5o them in parallel position with the under side of abox or body by means of bolts, or in any suitable way.

A2 is the rear axle.

is a pin projecting forward from the center ot' the axle into the tubular end or socket 55 7c of' the reach m, which reach is preferably made of' tubular wr0ughtiron,and plvoted to the front part of the carriage by means of a bolt, fifth-wheel, or in any suitable way.

a is a collar formed or xed to the central 6o portion of the reach m.

r is a swivel-coupling device, consisting of' two plates having` seinicircular bends in their centers and pert'orations in their ends, conibined with the front ends of' the hounds and 65 braces s by means of' screw-bolts, to encircle the reach m in front of' its collar n in such a manner as to restrict the rear carriage from longitudinal or backward and forward movement relative. to the reach and front carriage, 7o and also in such a manner as to allow the rear axle and carriage vbratory motion relative to the reach and the box or body mounted upon the complete gear.

I am aware that a jointed or divided reach has been used toallow the rear axle to vibrate relative to the front axle and box or body. I am also aware that braces extending from the rear axle have had a Swivelconnection with a continuous solid reach thatextended through 8o a box fixed to the rear axle in such a manner as to allow a vibratory motion tothe rear axle relative to the continuous reach; but my manner of' pivoting a continuous reach tothe rear axle by meansofa pin and socket is novel and advantageous.

I claim as my invention- 1. In a carriagegear, the combination ofthe duplex spring-bar consisting of the curved bars C, having eyes d, and the straight bars 9o j', the plate g, having gudgeons l, and a spring,

B, substantially as shown and described,i'or the purposes specified.

2. Ina running-gear for wagons and carriages, thecombinationof'afronta.xle,aspring, 95 two curved springbars, each having an eye,

a plate having gudgeons to engage the e) es ofthe spring-bars, a rear axle having a fixed piu projecting forward from its center, braces having a divided collar or coupling at their roo front ends, and a continuous reach having a socket at its rear end, substantially as shown and described, for the purposes specified.
